Yeah, people are smart though. Like if you’re good at getting food you find the person who’s best at violence and promise to get them plenty of food if they protect you from the other violent people. Maybe you divide up the work among the good at food getting people and the good at violence people and pretty soon you got yourself a little society going.

people capable of violence don't need to be smart, because they're capable of violence.

the point is, you cant rely on a scenario where society breaks down, that survivors will act more rational then than they do now.
